why don’t they look into ways that cars might cause fewer injuries instead of abandoning the injured?

I'm pissed they're repaving the streets near me but they're not taking the time to make them any safer. No curb extensions or daylighting. Certainly nothing so extreme as a separate bike lane.

One easy such thing, is puttling a piece of metal over a tractor trailer's wheel area, so you get deflected if you go under and not chewn up and spit out. It's voluntary and few trucks have it on them yet but a bunch of little stuff like that could help.
